can anyone help tell me what the domain of this function is please
f(x) = 1
sqr root of (1-x)(7+x)
The domain is all values of x for which the function is defined.
I'll give u one place that it's not defined.........
So are you familiar with interval notation?
@OP: Since is required, the interval is most easily found by drawing a graph of the parabola and looking for the values of x such that y > 0.
